What Are Acoustic Guitars Made Of? | Wood Choices Explained

Acoustic guitars are made primarily of wood, with spruce tops, mahogany or rosewood backs and sides, and ebony fingerboards being the most common combination.

For the full breakdown, see our best Acoustic Guitar With Accessories guide.

When you pick up an acoustic guitar, you’re holding a carefully engineered assembly of wood chosen for both tone and durability. The specific woods used shape the instrument’s sound, weight, and price. While most players care about how a guitar sounds, understanding what goes into it helps you make smarter buying decisions — and appreciate why two guitars can look similar yet cost wildly different amounts.

Here’s exactly what acoustic guitars are made of, part by part.

What Woods Are Used For Each Guitar Part?

Different parts of the guitar serve different jobs, so builders use different woods for each. The top, which produces most of the sound, gets different treatment than the neck, which needs stiffness and stability.

Yamaha’s instrument guide identifies the standard material assignments used across most acoustic guitars. The top is almost always spruce because of its resonant qualities. Back and sides are commonly mahogany or rosewood, which add warmth and projection. Ebony is favored for fingerboards and bridges because it’s dense, smooth, and wears well. Necks are typically mahogany or maple, sometimes reinforced with strips of other wood for extra stability.

Here’s the breakdown for a typical acoustic guitar:

This combination is standard, but it’s not the only recipe. Some colorful guitars use maple for the body because the wood is naturally white and takes paint well, according to Yamaha. Others swap in rosewood for the fingerboard or use sapele — a mahogany relative — for back and sides. Builders experiment constantly, which is why two guitars from the same factory can sound noticeably different.

Is Wood Always Used, Or Are There Alternatives?

Wood remains the dominant material in acoustic guitar construction, but it’s not the only option. A peer-reviewed review of guitar materials found that many wood species are in active use, with ebony, mahogany, and spruce among the most common. However, modern guitars increasingly include non-wood components in specific places.

Martin Guitar’s wood guide highlights Richlite, an FSC-certified composite material used in guitar construction. It appears on fingerboards and bridges on some Martin models, offering durability and consistency that natural wood can’t always match. Composite materials like Richlite resist humidity changes better than wood, which appeals to players in dry or humid climates.

Strings are always metal or other non-wood materials, and saddles, nuts, and some bindings often use bone, plastic, or composite. But the core structure — top, back, sides, neck — remains typically wood-based. Even guitars that use composites for key parts still build the soundboard from wood in most cases.

Here’s the honest caveat: “tonewood” is a broad, imprecise term. Wood species vary widely by maker and model, so no single wood list fits every acoustic guitar. A budget guitar might use laminate wood — thin layers glued together — for the back and sides instead of solid wood. That’s not necessarily bad; laminated sides are more resistant to cracking. But solid wood generally resonates better as the guitar ages.

Does The Wood Really Change How A Guitar Sounds?

Yes, and this is where materials get interesting. The top matters most — it’s the soundboard that vibrates when you pluck a string. Spruce is prized because it’s light yet stiff, responding quickly to attack and producing a clear, projecting tone. Back and sides influence the guitar’s character more subtly, adding warmth or brightness to the sound.

Mahogany bodies tend to produce a drier, punchier tone with strong mids. Rosewood adds bass response and shimmering overtones. Maple, which is denser, projects clearly with a brighter voice that suits some playing styles.

This is why two guitars made from different woods can feel completely different in your hands. A spruce-and-mahogany dreadnought and a spruce-and-rosewood auditorium guitar share the same basic shape but sound nothing alike. When you’re shopping, the wood combination is the single biggest factor in the guitar’s voice — after the player’s own technique.

FAQs

Do cheaper acoustic guitars use real wood?

Most do, but the quality and construction differ. Budget guitars often use laminate wood for the back and sides, which is real wood pressed into thin layers. The top is usually solid spruce even on entry-level models. Laminate construction is durable and humidity-resistant, though it doesn’t resonate as richly as solid wood as the guitar ages.

What is the best wood for an acoustic guitar top?

Spruce is the most widely used and preferred top wood, according to Yamaha’s instrument guide, valued for its resonant qualities and light weight. Sitka spruce is the standard for steel-string guitars, while European spruce appears on many higher-end models. Cedar is a common alternative on classical guitars, offering a warmer, more immediate response.

Are any acoustic guitars made without wood?

Fully non-wood acoustic guitars are rare and specialized. Composite materials like Martin’s Richlite appear on fingerboards and bridges in many models, and some companies build entire bodies from carbon fiber. These guitars resist humidity and temperature changes better than wood, but they remain a niche choice rather than a mainstream alternative.
